This invention comprises novel and useful improvements ina concrete building block construction and more specifically pertains to an improvedcon'struction of building blocks which closely. simulates the. artistic effect of a colonial shingle finish in a hollow concrete building block.

The presentapplication is a continuation in part of my" prior application Serial Number 453,588. filed .August' 4, .1942, now abandoned.

The principal object of this invention is to provide aiconcrete, hollow building block which will'provide alap joint with adjacent building blocks in .a' masonry. construction to give an artistic colonial shingle finish to a structure.

Additional important objects reside in provid-inga buildingblock'having an improved interengagin'g connection in-relation with adjacent blocks in a masonry construction.

Yet another important object of the invention is to provide a building .block having both vertical and horizontal air spaces therein for providing improved insulating .qualities against moisture,- heat and cold in building construction.

A still further important purpose of the invention consists in providing a building block which shall be comparatively light yet very strongand durable, -rnay be easily assembled and is withal highly eificient for thepurpose intended.

These, together "with various ancillary objects which: will laterbecome apparent as the followingdesoription proceeds; are attained by this device; a preferredembodiment of which has been illustrated by way of exampleonly, in the accompanying drawings wherein:

Figure 1 is a perspective view ofa portion of amasonry construction, parts being broken away to show constructional details thereof, illustrating the improved building block in accordance with-this invention;

s Claims. (oi; 72--ss) to be subsequently-set forth;

Figure 2 is a top plan view of a building I 2 block which is reverse with respect to that shown in Figure 6.

Referring now more-specifically to the accom panying drawings, wherein like numerals'- desig nate similar parts'throughout the variousviews; reference is-"made first'to Figure 1-'-5for ab'etter understanding of the construction of the-main buildingblock in accordancewith this invention.

The'mairr building'unit or bloclrdesignated generally at in may be-constructed of any suit= able cementitious or cinder-buildingblock ma terial, and is ofgenera'lly standard configuration and proportions,comprising a pair of outer'walls defining front andbacksurfa'ces '12 and we: spectivel'y, which are disposed parallel to each other and between-which is positioned apair-of parallel, evenly spaced inner .wallsiS and [8: As shown-best in Figures-2-and 4, the front'wall l2 and intermediate wall I6 are spaced 'at their extremities by connecting webs Ziihaving grooved upperand lower surfaces 22 forproviding Icingi tudinally extending passageways between said walls. Similarly, thereariwall 11.4' and-adjacent intermediate wall I 8 r are provided-with spacing websflZEl having similar channels 22'for the same purpose just mentioned. 7

As shown best'in Figures 2-and 5; the inter: mediate Walls [6 and 1 l S are 1 laterally spaced by a connecting web 24 having on its upper'surface recessedgrooves 26 "establishing longitudinal passageways through the block "for the purpose" At their upper and lower edges, the-partitionsi2, M, iii and I8 are provided with laterally postioned; longitudinally extending but reversely arranged shoulders Qtconstit-uting interengag ing means for the superi-mposed 'andsuperencumbrance building block-unit of a-masonry con struction; It will be noted.- that; the abov ade scribed web-construction provides lateral ;rei n-' forcing means throughout the hollow building block at three points along its=-length;;and at a po'nt intermediate its length-.- At the same time, the interengagement of the shoulder'portions 28 serves to'reinforce the masonry construction and further bodythe same as well as establish feel; for the plurality oflongitudinallyextending-pay sageways between the three partitions or wall members.

As shown best; in- Figure 2, the partition wall" members l4, l6 and i3 of the unit it! are provicled with shouldered portions 39 at eachend thereof, these shoulder-portons-being oppositely disposed whereby they mayyestablish an interengaging i and-"sealing relation with the adjacent longitudinally aligned building units as shown in Figure 3. The front wall l2 of the unit is provided with a downwardly and outwardly flaring surface 36 which lower portion is shown at 38 to overlap in the form of a shingle lap with the upper shoulder portion 28 of the block in the next course below. By this means, the surface 36 gives a colonial shingle finish to a masonry construction as clearly set forth in Figure 1.

As shown best in Figure 3, it will be seen that in adjacent courses of masonry, block joints are positioned in staggered relation to each other, in a conventional design, whereby the webs 20 and 24 combine a plurality of vertically extending longitudinally spaced air passages interposed between the four walls of the building units. As will be noted, each of the vertically extending passageways is in communication with others in the same row, by means of the above mentioned horizontal or longitudinal channels designated at 22 and 26.

The front and rear edges upon the vertical ends of the front wall l2, are alternately provided with tongue and groove portions 32 and 34 for engagement with corresponding comp.ementary portions of the adjacent and longitudinally aligned building units.

In order to form corners for masonry wall constructions and the like, the arrangement shown in Figures 1, 6 and 7 may be resorted to. For this purpose, generally L-shaped building block units 4!] and 42 are provided, which are reversely positioned with reference to each other. Thus, the perpendicular, short extremities of these blocks are reversely disposed relative to each other for making right angled turns in masonry construction in opposite directions. These units are identical in construction as to their main leg, with the building unit l; and each of the four longitudinally extending walls 44, 46, 48 and 50 of Figure 6 and 52, 54, 56 and 58 of Figure '7 are constructed and spaced as in the embodiment of Figure 10. Each of these walls, however, is perpend'cularly disposed at its lower end thereof as at 45, 41, 49 and 5| in Figure 6 and 53, 55, 5'! and 59 in Figure 7, for sealing and interengaging relation with an adjacent building unit In of the angularly disposed course masonry.

' In the corner blocks 40 and 42, the same shiplap construction, with a passage arrangement, and inwise and upper and lower sealng engagement is provided as in the main bui ding unit II].

From the foregoing, it will readily be seen that there has been provided a building block construction which in add'tion to all of the known advantages of a hollow, multicell and multipassage cement building block also possesses an improved interengaging and sealing relation with adjacent blocks in a masonry construction, and in addition provides in one unit a book capable of producing a colonial shingle finish to various building construction.

Since various modifications will readily occur to those sk'lled in the art after consideration of the foregoing specification and the accompanying drawings, it is not intended to limit the invention to the exact construction shown and described, but all suitable modifications and equivalents may be resorted to fall'ng within the scope of the appended claims.
